How car I insert an image in a master form using asp.net?

So you want an image to sit behind a form that a user fills in?

You could do it with CSS (Cascading style sheets)

So in the header section of your page, you could type something like:

<style type="text/css">

body
{
    background-image: url('yourimagefolder/yourimage.jpg);
}


</style>

Maybe if you be a bit more specific about what you are trying to do we can help you further

No, sorry I mean only for background how can I insert it, I see something of a URL, but I don't know how to get the url of the image. I know it should be simple, but I'm copmpletely newbie in ASP.

Thanks for everything
